CAR-COUPLING.

thecar adjacent;and its object is to render the operation ofcoupli ngmore convenient and safer than heretofore.

It consists in the arrangement and combination, in a suitable draw-head,of alink formed with an eccentric and of a movable cam-block actuated bysuitable rods orlevers for the purpose of controlling the position ofsaid link either from the top or sides of the car.

In the accompanyingdrawings, Figure 1 representsthe adjacent ends of thetwo cars coupled together by my improved device, one side of thedraw-head of each coupling being partially broken away to show themovable cam-blocks. Fig. 2 is anrisometrical perspective of one end of acar provided with my improved coupli'n g. Fig. 3 is an isometricalperspective of the camblock, and Fig. 4 a similar view of a linkprovided with the eccentric.

The draw-head A consists of a hollow neck or body, a, with a solid heador butter-plate, a, provided with a slot or opening, o in the face ofthe buffer-plate for a link, and a well-hole, a for a coupling-pin, a,near and just back of the buffer-plate a in the 'draw-head, for use whenit is desired to couple with a car provided onlywithordinarylink-and-pincoupling. Thedrawhead proper and buffer-plate ahave upon the lower or under side a horn or projection, b, at the bufferend extending downward for the purpose of holding or retaining thecouplingframe 0, which is thrown around the horn or projection b, whichcoupling-frame O locks or couples the two' draw-heads together. Thiscoupling-frame O has two m0vements-an upward movement and a downwardmovementboth in the arc of a circle and Working outside of the lower orunder side of'the draw-head a and buffer-plate, and is raised up andaround the horn or projection b of both the draw-heads. Thiscoupling-frame C may be made of any shape, and forged, pressed, or castfromiron, steel, or other metal, and of onecontinuous piece of metal, soas to retain all the strength of such metal, and is welded together atitsinner end to form an eccentric, c, said eccentric movingperpendicularly up and down or following the face of the cam. Thecouplingt'ramefl is operated from the top of the car, or from either orboth sides of the car. The coupling frame or link 0 is raised into itsposition for coupling or connecting the opposite draw-head each to theother by an eccentric or cam biock, D, which eccentric or cam is a partof or is attached to the lower end of the perpendicular or service redat, and which cam D leans or rests directly upon the inner or smallerend, 0, ot the coupling frame or link. This cam D is moved within arecess or wellhole, 6, made in the body of draw-head A, open at thelower or under side to allowthe necessary motion for the cum I). Thecamblock has two flaring holes or cores, d d, cast, formed, bored, orpunched into it on opposite sides for the purpose of receiving the endsof the side rods, E E, which raise or lower the cam D in connection withthe service or upright rod (1. By depressing or bearing down theperpendicular or service rod (1 the'cam D is depressed upon theinnerorsm'allend, c, of the coupling frame or link 0, causing it to riseinto its proper position forcoupling with the opposite drawhead. Thisinner or small end, a, of the coupling-frame O is in the form of aneccentric bearing, 0, which moves or travels upon the face of the cam Das it is' depressed or raised to lock or unlock the connectioubetweenthe two draw-heads. This cam D has two movements-an upward movement andadownward movement--operated by hand by the perpendicular or service rodd, and moving in a recess or well, 0, madein the neck orbody of thedraw-head A, together with theinner or small eccentric end of thecoupling-frame 0, all operated from the roof of the freight-car, or fromeither or both sides of the car, at the end, and from the ground at theoutside of the car. The cam D may be made triangular, convex, concave,flat, or square upon the face, as may be required. The coupling frame orlink 0 may be made of any shape, circular, oblong, elliptic, or square,terminating in an eccentric,

c. The coupling-frame G hangs perfectly free, giving all the lateralmotion that is required by the swaying of the cars. 1

The service or upright rodhas two auxiliary or parallel rods, E E,extending from each side of the service or upright rods to the lower orunder side of the cam D to the outer side, and at the end and underneaththe end sill of the car', for the purpose of coupling or uncoupling thedraw-head D from the ground. Thus I have complete control of themovements ot'thc coupling-frame G from the top and at either end and atboth sides of the car, and from the ground. These several parts may bemade of cast or wrought iron, steel, or other metal. ,What I claim, anddesire to secure by Letters Patent, is-- 1. In a car-couplingsubstantially such as described, the pivoted upwardly-engaging linkprovided with the eccentric, in combination 20 with movable cam-blockwhen operating in conjunction, substantially in the manner and for thepurpose set forth.

2. In a car-coupling substantially such as described, the movablecam-block provided with 2 5 and capable of being actuated by either thevertical rod from the top of the car or the auxiliary side levers forthe purpose of controlling the position of the upwardly-engaging link,substantially in the manner and for the pur- 3o poses herein set forth.
